They fly over the bay with the greatest of ease: "Mama! I am going to be an acrobat and sail around the world!"

French "sailing acrobats" Franck and Delphine Rabilier are a charming and athletic pair who perform in the rigging of a 40-foot yacht called La Loupiote they sail from port to port.

It's like an old-fashioned circus wagon, just waterborne. The couple left France in 2004 to sail around the world and now have two daughters, ages 3 and 11.

To fund this journey with their children, they perform acrobatic shows from the mast, boom and rigging inspired by their performing experience in the circus, dance and theater.

The Rabiliers are doing their first Bay Area performances today and Sunday in Sausalito. The free shows are at 2 and 4 p.m. each day, though donations are requested. Shows are suitable for audiences of all ages and last 20 minutes.

This weekend's performances are in the water off KKMI Marine Services, 420 Harbor Drive, Clipper Yacht Harbor, Sausalito.

Yacht life reality TV: The debate about mega-yachts on the San Francisco shoreline rallied many, but a major cable network has a different take. Reality TV casting producer Scott Goldstein sent an e-mail to yacht clubs this week seeking stars for his next show.

"I am currently casting gay men who have experience as a crew member sailing," he wrote.

The show will revolve around the staff of a high-end yacht as they travel around the world. "Personality is a must," he says.
